Turbo installation / dyno tuning?

Hello
I am planning my turbo installation in my miata.
I have these parts so far.
Td04 16g turbo
12:1 Tial BOV
10:1 Vortech FPR
Flyin miata cat back exhaust
Intercoolor with piping, turbo manifold, Downpipe,
Denso 430 CC injectors.
boost gauge,
a/f ratio gauge

I am confused about a few things,
1. Since these are high ratio BOV and FPR, would running at about 6-8 PSI of boost affect my installation?
2. With the following items I have now, is it possible to complete my installation and get it dyno tuned? (dont know how they can tune it since BOV and FPR is not adjustable)
3. If I was to buy a standalone EMS (probaby Meqasquirt) , I dont need a FPR?
4. If i buy a standalone EMS, does that mean I dont have to go dyno tune it? I just program it myself?
5. If I buy a standalone EMS, is that what people at dynotuning places tune? Or do they reprogram your stock eu?

Thanks guys, I know these are alot of questions, but I appreciate your answers.
All the best.

Also, would you guys recommend getting anything else for my installation?  

1. You'll be fine
2. You can't tune a car without a proper EMS.
3. You'll still need the FPR.
4. You'll need to have experience in tuning a car, ie. listening for knocking, advancing and retarding timing, knowing proper a/f ratios, access to your own dyno, etc. Every car is different so you can't just input some data and it'll magically work, so you'll need to adjust accordingly. If you're already asking these types of questions, let a pro handle it.
5. Again tuning requires a proper EMS, either piggyback or standalone. My advice to to either get a GReddy E-Manage Ultimate (piggyback) or an AEM EMS (standalone).

GL with your build, but the most important step first is to get your car running, then worry about tuning.  

Forgot one more thing: NGK Iridium spark plugs in a colder heat range. You may or may not need them in a colder heat range, but def. switch out to NGK Iridiums or the simple NGK V-Power copper spark plugs.
